Laptop locks itself more and more often?

Unfortunately I have the problem that my laptop locks you more and more often by itself. Windows 10 is installed. It then shuts down briefly. There's currently no battery in it, so it is always attached to the charging cable. This has happened at ever shorter intervals lately. What could be the reason?

What exactly does he mean by locking himself? Does it go down and then not up at all? Can you still enter a password? Has the password entry been activated? Or does it just switch itself off and then start up again? Do you have the possibility to use a battery to check the behavior again? Or to get into what is called Safe Mode? For example via a command prompt? You can also find more information on Safe Mode Windows 10 on the Internet.

First of all, thank you for the detailed answer. It locks itself, but you can turn it on again immediately afterwards without having to start up. Unfortunately, I can't use a battery. Can you break something yourself in safe mode?
